Detection if Home assistant companion is dead

Mobile Apps Home Assistant Companion for Android
1

I want to create a template sensor that shows me if a phone with home assistant companion is communicating with my home assistant installation or not.

Example: A phone with home assistant companion gets into an area with no data signal.

I want that template sensor to change from “alive” to “dead” after 5 minutes of missing communication.

Which of the companion sensors would yield that information? I tried hard to find one to “milk” that information, but didn’t find anything suitable.

Thanks
Frank

location updates come in every 1-3 minutes with duplicate locations not sending updates for 15 minutes, the others will have more variability.

I created a template sensor that detects when my plant sensors are not delivering updated data, something you could re-use maybe? If you could combine it with location or something.

- name: Plant 1 stale sensor

    icon: mdi:flower

    state: >-

      {% if as_timestamp(now()) - as_timestamp(states.sensor.plant_1_illuminance.last_updated) > 43200 %}

        true

      {% else %}

        false

      {% endif %}

When the phone is lying on a table (it is static for several hours), there won’t be a location update, right?

So what would be a sensor with a better variability?
